  • Patent number: 10607149
    Abstract: A cascading microwave isolator (cascade) includes a set of Josephson devices, each Josephson device in the set having a corresponding operating bandwidth of microwave frequencies. Different operating bandwidths have different corresponding center frequencies. A series coupling is formed between first Josephson device from the set and an nth Josephson device from the set. The series coupling causes the first Josephson device to isolate a signal at a first frequency from a frequency multiplexed microwave signal (multiplexed signal) in a first signal flow direction through the series coupling and the nth Josephson device to isolate a signal at an nth frequency from the multiplexed signal in the first signal flow direction through the series.

  • Publication number: 20150134677
    Abstract: A method, system, and computer program product for amorphous data preparation for efficient query formulation are provided in the illustrative embodiments. A normalized form of representing a set of data cubes is selected, wherein the set of data cubes includes a first data cube conforming to first data representation and a second data cube conforming to a second data representation, and wherein the normalized form selects a third data representation to represent the data of each data cube in the set. A transformation is applied to the first data cube to represent the first data cube using the third data representation to create a normalized first data cube. A set of metadata elements corresponding to the normalized first data cube is computed. The normalized first data cube and the metadata of the normalized first data cube are saved in a data store.

  • Publication number: 20130124514
    Abstract: In response to a query of discernable facial attributes, the locations of distinct and different facial regions are estimated from face image data, each relevant to different attributes. Different features are extracted from the estimated facial regions from database facial images, which are ranked in base layer rankings by matching feature vectors to a base layer ranking sequence as a function of edge weights. Second-layer rankings define second-layer attribute vectors as combinations of the base-layer feature vectors and associated base layer parameter vectors for common attributes, which are matched to a second-layer ranking sequence as a function of edge weights. The images are thus ranked for relevance to the query as a function of the second-layer rankings.

  • Patent number: 7760630
    Abstract: The filtering operations normally performed at the output port side of an Infiniband (or similar protocol) routing switch are performed in parallel at the input side to prevent data packets from being placed on a queue from which they would ordinarily ultimately be discarded, thus removing “bad” packets that would normally have a negative impact on the bandwidth of the switch. Bad data packets thus do not consume space in a central queue nor bandwidth in a crossbar switch.

  • Patent number: 7657756
    Abstract: Methods and apparatus that may be utilized to reduce latency associated with encryption based on externally stored security metadata are provided. When encrypted data is accessed for the first time, a cache line containing corresponding metadata used for decryption may be placed in an internal security metadata cache. If that data is accessed again, it may be retrieved without accessing external memory, thus reducing latency. Further, if adjacent data is accessed, the cached line may contain sufficient metadata to decrypt the adjacent data. As a result, a separate operation to access metadata for the adjacent data may be avoided, thus reducing latency.

  • Patent number: 7290252
    Abstract: A program which is linked or bound by reference (referenced program) into one or more other programs supports multiple valid export signatures, each corresponding to a respective version of the referenced program. When a program is built, it records the current signature of each referenced program it is bound to. When subsequently determining whether to rebuild the program, the previously recorded signature of any referenced program is compared with all currently supported signatures of the referenced program, and only if none of the supported signatures matches does the program need to be re-built to ensure compatibility with the referenced program. Preferably, the referenced program is a program library containing supporting procedures, intended to be used by multiple applications programs which are bound to it.

  • Patent number: 7216141
    Abstract: A 4-to-2 carry save adder with a reduction in the delay of outputting the sum and carry bits. The 4-to-2 carry save adder may include a lower order full order coupled to a higher order full adder. The carry save adder may further include a logic unit coupled to the higher order full adder where the logic unit is configured to generate a carry bit to be inputted to the higher order full adder that normally would be generated from the carry save adder located in the previous stage. By generating this carry bit (carry-in bit) in the current stage and not in the previous stage, the delay of the carry-in bit inputted to the higher order full adder is reduced thereby reducing the delay of outputting the sum and carry bits by the higher order full adder.

  • Patent number: 7035791
    Abstract: A method for speech synthesis includes receiving an input speech signal containing a set of speech segments, and estimating spectral envelopes of the input speech signal in a succession of time intervals during each of the speech segments. The spectral envelopes are integrated over a plurality of window functions in a frequency domain so as to determine elements of feature vectors corresponding to the speech segments. An output speech signal is reconstructed by concatenating the feature vectors corresponding to a sequence of the speech segments.

  • Patent number: 6904040
    Abstract: A network handler uses a DMA device to assign packets to network processors in accordance with a mapping function which classifies packets based on its content, e.g., bits in one or more header fields. Preferably, the mapping function is implemented as a hash function, which uses a predetermined number of bits from packet as inputs. The result of this function specifies the processor to which the packet is assigned. To make implementation manageable in a high-traffic environment, each processor may be equipped with a queue, which holds pointer information. Such a pointer provides an indication of the area in memory where incoming packet resides. The network handler is particularly useful in a Fiber Channel environment, where the hash function may be implemented to assign all packets from the same sequence to the same processor, thereby resulting in improved processing efficiency.

  • Patent number: 6851034
    Abstract: A method for managing computer memory includes maintaining multiple sets of free blocks of memory wherein a free block is added to a set based on its size. In response to a request for a block of a request size, a set of blocks is searched for a free block which is at least as large as the request size but smaller than the request size plus a threshold. If such a block is found, the block is allocated in its entirety if such a free block is not found, a block at least as large as the request size maybe split and the request satisfied with the resulting split block. Methods for managing a block of contiguous persistent memory or storage and for coalescing adjacent free blocks using header information are also described.
